This crossover accepts the input signal
from a 2-channel input source, using
either low level RCA outputs or high
level (speaker) outputs from your head
unit.
Input source selection
The EC10B features both low level (RCA)
inputs and high level (speaker level) inputs,
enabling you to generate a two-way sys-
tem from virtually any head unit you may
own.
If your head unit has RCA Left and Right
Channel outputs, you should choose these
for your EC10B input source, since the
quality of sound reproduction is best when
using these.
However, if your head unit lacks RCA
outputs, you can use the speaker outputs
from the head unit as an input source for
the EC10B. Simply follow the wiring dia-
grams in this manual closely to make sure
you get the best performance possible
and avoid damaging your head unit.
Input and output connections vary depending on the system application. Examples
are shown in system diagrams on the pages which follow in this manual. Always use
high quality RCA cables for low level input and output connections.

The EC10B has internal ON/OFF
circuitry which responds to turning ON
or OFF the head unit of your car audio
system. This requires that your head
unit have a remote turn-on lead
available on the rear panel (which most
head units have).
With this convenient remote turn-on/off
feature, you never have to worry about
turning off the power to the equalizer
when you shut off the audio system.
When you are confident all connections
have been made correctly:
1. Power up your audio system by
turning on the head unit.
2. Set the volume control on the head
unit to about 3/4 volume, and adjust
the EC10B’s Speaker Input Gain
controls for each channel to just below
the level of distortion.
Further fine tuning of the controls on
the EC10B and the input levels of the
connected amplifiers may be
necessary to obtain satisfactory results.
If you are unsure about how to fine-
tune the system, please consult with
your Planet Audio dealer.
